A CORPORATION QF YORK CHUTE STRUCTURE Y Application fled February 2, 1931. Serial No; 512,831.

This invention relates to chute structures, and more particularly to certain improvements in the construction of conducting chutes and the means for mounting the same in .xed relation to the wall of a building undergoing demolition or erection for the purpose of receiving dirt .and building dbris and conducting the same to a suitable collection hopper. A temporary chute structure of this type is disclosed in my pending apf plication for patent Serial No. 464,172, filed J une 27, 1930, and my present invention has for its general object and purpose to improve the construction of the chute sections in certain particulars whereby they may be assembled in superposed relation and rigidly connected with spaced vertically extending supports with greater ease and facility and also very coinpactly arranged when disassembled so that they will occupy relatively little space in transportation or storage;

It is a further object of my invention to provide individual chute sections of sheet metal construction which will` be relatively light in weight, each of said sections being formed means to removably receive closure panels for the open sides thereof.

More particularly, in one embodiment of the invention, thesheet metal chute sections are of substantially U-shaped form in cross section, the side walls of which are provided with longitudinally extending channels at the open side of the chute section to receive the closure panels, the walls of the chute section at their opposite ends being` provided with continuous outwardly extending reinforcing flanges. It is also one of the detail features of my invention to provide means permanently carried by said flanges for detachably and rigidly securing the superposed chute sections in assembled relation.

Vith the above and other objects in view, the invention consists in the improved chute structure and in the form, construction and relative arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawing, and subsequently incorporatedV in the subjoined claims.

`members 9 arranged at Figure l is a fragmentary side elevation showing the manner of mounting and supporting the chute structure with respect to theV wall of a building;

Fig. 2 is a front elevation on an enlarged scale; i

F ig. 3 is a horizontal sectional view taken on the line S-Sof Fig. 2, and

Y Fig. 4 is a fragmentary perspective view of two chute sections in separated relation to each other. As herein shown, the chute structure may berbuilt up of any desired number of units or sections as required, the saidV sections as they are successively assembled. in superposed Y relation, being securely and rigidly fixed to l the spaced vertically disposedsupporting elements which have previously been arranged and secured in properly spaced relation Vto thev face. of the building wall. As herein shown, the spaced vertical supports `for the chute structure each consists of a plurality of lengths of metal tubing indicated at 5, which may be of any desired length and are yprovided at their ends with suitable coupling means whereby said lengths of tubing may be detachably connected with each other. Thile these vertically extending supports might be anchored orffixed with respect to the wall of a building in vario-us ways, as one simple and eiicient means for this purpose, I preferably use the device disclosed inimy copending application above referred to, and consisting of the short rods or tubes 6 securely fixed at one of their ends to the vertical tube sections 5 by means of the coupling devices indicated at 7 and extending at right angles to saidtube sections and inwardly through the ,window openings of the buildingwall WV. The inner ends of these short tubes 6 Vices 8 with the vertically disposed tubular the inner fa-ce of the building wall and at opposite sides of the window opening.

,are similarly connected by the coupling de- Y ioo f sively The chute structure comprises individual units or sections 10. The body of each of these chute sections may be conveniently formed from sheet metal of the requisite gauge, pressed or die stamped into general trough shaped form, roughly U-shape in cross section and preferably tapering or decreasing in width from the open side of the chute section to the opposite closed side thereof, as clearly seeninFig. 3 of the drawing. Each of the lateral side walls 11 of the chute section has a continuous longitudinally eX- tending inwardly opening lchannel 12 formed on its edge at the open'side of the chute section.

To the opposite ends of the walls of the `sheet metal chute section outwardly projecting continuous flanges 13 are welded or otherwise permanently secured. The ends of these flanges abut closely against the Walls of the channels 12, providing adequate reinforcement thereof. at the endY of the chute section,

said ends of the flanges projecting late-rally beyond the outer walls of the channels 12, and

thus obviating distorting .or bending of the ends of thel channels which might otherwise occur.

Y The channels 12 of each chute section'adjacent the opposite ends thereof have suitably secured thereto the clamping or coupling devices indicated at 14: which are of more or less conventional form, and enable the proper engagement thereof with the outer sides of the supporting tubes 5, as the chute sections are successively assembled.V

The flange 13 on one end of each chute section is provided with the openings indicated at 15and at corresponding points, the flange on the opposite end of the chute section is provided with the upstanding studs 16. Thus, it will be understood that in assembling the chute sections in superposed relation, the studs 16 of one section are received through the openings 15 in the flange of an adjacent chute section. Locking keys 17 are connected by short chains 18 permanently to one of the flanges 13 of each chute section. These keys are preferably in the form of tapered pins adapted to be driven tightly into correspondingly tapered transverse openings 19 formed through the studs 16. Preferably, as a sound deadening means, I interpose between the adjacent flanges of the superposed chute sections a gasket strip 20 of paper,vasbestos or other suitable material, which of course is likewise provided with suitably located openings to receive the studs 16. As the chute sections are succesassembled, the locking pins 17 are finally driven through the openings 19 of the studs 16 and have bearing contact upon ,the upper surface of the flange 13 on the lower end of the upper chute section. Thus, the chute sections will be securely held in assembled relation and relative lateral shifting .nested one within another. chute sections together with the panel memd OIl.

movement of the end of one section relative to the other eectually prevented.

Preferably, I also provide each of the flanges 13 and the interposed Gasket strip 2O at the opposite sides of the clhute section with additional openings indicated at 21 to receive the hooks of a block and fall or other hoisting means whereby the chute sections may be expeditiously handled in the erection or dismantling of the chute structure. From the foregoing description, it will be seen that by means of my present improvements, the chute structure may be easily and quickly built up Ato any required height. After the chute sections have been assembled in the manner above described, and rigidly connected Vwith the vertical tubular supports 5 4by means of the clamping or coupling devices 14, suitable Vclosure panels indicated at 22, which may conveniently consist of boards or planks of any desired length, are then inserted at their opposite longitudinal edges into'the channels 12 of the chute sections. Certain of these boards are provided with openings therethrough to receive thel outer ends of inclined feed or inlet chutes 23 which extend outwardly and through the lower ends of the window openings in the wall W as seen in Fig. 1 of the drawing. In order that the openings in the boards 22 may be properly located with relation tothe window openings which may be variouslyspaced vertically from each other in different building walls, additional supplementary panel sections of relatively short lengths may be enployed and 1 interposed between the main longer panel sections 22. These panel sections 22 tightly close the open sides Yof the chute sections, preventing the escape of dust therefrom or the entrance of water into the interior of the chute.

When the use of the chute structure is no longer required, it will be evident that thev several units or sections thereof may be readily disconnected andthe tubular supporting elements 5, 6 and 9 also quickly uncoupled. In view of the form of the chute sections, a large number of said sections can be easily bers 22 and the parts of the chute support can be very compaetly arranged in a comparatively small space for purposes of storage or transportation. The tubular elements 5, 6 and 9 may conveniently be placed within the nested chute sections while the boards or panels 22 can be placed over the open sides of said chute sections and finally the inlet Therefore, the ,A

liso

chute sections 23 may be superimposed thereu Thus the lateral dimensions of the knocked-down structure will kbe confined within very narrow limits.Y

I have herein shown and described an embodiment of my presentv improvements,

which I believe to be entirely practical andy assertief,l

serviceable for the purpose in view. While I have particularly referred to a preferred form of the sheet metal sections, it Will of course be evident that the sections canbe of various other cross sectional shapes as may be desired, also the several other detail parts of my present disclosure as herein referred to are susceptible of more or less variation in form, structure and arrangement, and it is therefore, to be understood that I reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied Within the spirit and scope of the invention as claimed.
